TO ALL WHOM IT MAY CONCERN: 7

Be it known that I, HUGH SANGSTER, of the city of Buffalo, in the county of Erie, and State of New York, have invented certain new and useful improvements in. Lanterns; and I do hereby declare that the following is a full and exact description thereof, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the arrangement of the springs and lower rim of the lantern for the attaching and detaching of the lainppot to and from the lantern; also in the manner of arranging and putting the springs together. In the drawings-- Figure 1 is a side elevation showing the lantern complete, with the lamp-pot partly detached Figure 2 is a partial section of the lamp-pot showing the ends of the springs, and a side view of that part of the springs which connects and holds the larnp-pot to the lantern.

Figure represents a side view of the lower rim of the lantern, showing one of the apertures into which the catches on the springs are forced when the lamp-pot is connected. There are two ofthese apertures, placed directly opposite each other.

Figure 4 is a plan view of the rim that surrounds the lamppot; the springs and catches are also shown.

Figure 5 is a view of one or" the springs; showing the manner in which it is put together.

Similar parts are represented by similar letters.

In fig. 1, A B G D E I and G represent the wcll-known parts of a lantern, the top, bail, guards, glass, and lower rim. H is the rim surrounding the oil-pot, to which the springs are fastened by rivets or solder, as shown at N N, fig. 4. I I are the springs. M M are two loops for preventing the springs from being drawn out too far while in the act of disengaging the lamp-pot. J J are the catches which are attached to or form a part of the springs. K is the lamp-pot, and L the bottom.

I construct my lantern of the usual materials, tin plate, copper, or brass. The springs and catches are so arranged that the lantern and lamp-pot may be connected by simply pressing the lower part of the lantern down into the rim surrounding the lamppot, which operation forces the springs out, and then turning it around until the. catches I I meet and spring into the apertures R, of which there are two, directly opposite each other, in the'lower rim G. It is disconnected by pressing out only one spring and tipping the lamp-pot a little to one side, as as shown in fig. 1; it is then easily taken off. The springs are made of two pieces, as shown in fig. 5; they are hent,'as at P P, which parts are then brought together and soldered, thereby forming the catch J. Thoymay be made of one piece of metal, and the spring bent in such a manner as to form the catch J, but I prefer putting them together in two pieces. The great ditficulty in. spring fastenings is their liability to get out of order in giving the necessary signals with railroad lamps; the pots are very liable to fall out, which fact has prevented the use of spring lanterns on railroads to a great extent. By my improvement I claim to have overcome these objections, and to have made a simple, strong, and reliable fastening.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the springs I I, catches J J, and rim Gr, with the apertures R, as and for the purposes hcrein substantially set forth and described.

2. I claim the springs, when constructed of the parts P P, as shown, fig. 5, and put together as described.
